*1 Liquid must allow for the passage of an ultrasonic pulse, as well as not contain large air pockets or excessive bubbles. Detection may be unstable due to the type and status of the pipes.*2 Perform derating depending on the ambient temperature and liquid temperature when using an AC power supply.*3 The zero cut flow rate can be changed in the settings.*4 This value is guaranteed by KEYENCE inspection facilities. Errors will be introduced by the type and status of the pipes, the type and temperature of the fluid, and the zero cut flow rate.*5 This is the value when considering linearity + span error + repeatability in a stable environment of 25°C 77°F.*6 It is possible to enhance the precision of zero point error by performing an origin adjustment.*7 IO-Link: Compatible with Specification v1.1 / COM2 (38.4 kbps) The setting file can be downloaded from the KEYENCE website.
